Is it wrong to use Metal-Roughness-Specular etc. maps in sRGB mode?
It is technically incorrect not to use the “non-color” color space you’re using is non-color, but the result will not be horribly incorrect. as another user said, values will be shifted a bit, and normal Maps the most because they use all three channels. But anyway, why do you not want to set this? There is thankfully a way to do it with the python API, as I’ve discovered when needing it for such a purpose.
